Applications of W3G800-LU21-36/F01
Typical applications for the W3G800-LU21-36/F01 include:
Key Features of W3G800-LU21-36/F01
Efficient 1,090 RPM Airflow Concept
The moderate-speed, large-diameter design delivers substantial airflow across wide coil surfaces.
29,175 m³/h Cooling Capacity
The published airflow supports large heat-rejection duties in dry-cooler and condenser equipment.
290 Pa Axial Pressure
The fan provides useful pressure for compatible heat-exchanger coils and outdoor equipment structures.
EC Part-Load Energy Management
Variable-speed control helps reduce fan power when ambient conditions or system load allow lower airflow.
Selection and Installation Notes for W3G800-LU21-36/F01
Confirm the 400 V supply, F01 electrical and software configuration, command signal, coil resistance, airflow direction, drainage, service clearance and fan-array sequence. Confirm final suitability against the required operating point and host-equipment documentation.
Why Choose the W3G800-LU21-36/F01?
It offers a practical balance of high airflow, broad 800 mm coverage and moderate-speed EC operation for energy-conscious heat-rejection equipment. Using the complete model designation helps prevent electrical, mechanical and control mismatches.
FAQ About W3G800-LU21-36/F01
Q1: Where can the W3G800-LU21-36/F01 provide the greatest efficiency benefit?
A1: It is especially useful where cooling demand changes and fan speed can be reduced during favorable ambient or part-load conditions.
Q2: Why should the coil face be kept clean?
A2: Fouling increases resistance, reduces heat transfer and forces the fan system to work harder.
Q3: Can several fans follow one coolant-temperature target?
A3: Yes, when a compatible controller coordinates speed and staging across the complete fan array.
Q4: What should be checked after a seasonal shutdown?
A4: Inspect blades, guards, cables, mounting, drainage and free rotation before restoring operation.
